United States Patent 80,660 WATER CLOSET BOWL BOTTOM CGNNECTEGN Philip J. Brewington, 6401 Emerald St, Austin 45, Tex. Filed Jan. 30, 1963, Ser. No. 254,926 2 Claims. (Cl. 285-60) This invention relates to water closets and has for its principal object the provision of a new and improved joint or connection between the usual brass closet flange or brass ring and the flange at the lower part of a water closet bowl, by replacing the usual bolts with two-piece anchoring devices, preferably largely of tough plastic material matching in color the ceramic bowl.

The disadvantages of the bolts presently used in this joint include the fact that often these are furnished in lengths to accommodate the largest thicknesses of bowl flange to be expected and thus they have to be laboriously sawed off to correct length, a task of quite awkward type. first because of the position the plumber must assume for the job; second because of the frequent accidental misplacement of the bolt as it topples into the cavity which exists under the slot in the brass ring; and third the usual need to provide a cover to hide the usual washer and the nut above it.

The anchoring device shown in this application avoids all of these disadvantages as it is standardized to accommodate any thickness of bowl flange, always stays in place, and is never unsightly as the head fits snugly on the top of the bowl flange as the screw embeded in the head cuts a groove in and may gradually enlarge the tough plastic upper part of the tubular portion of the stern which is inserted in and moved along the arcuate slot in the brass flange.

FIGURE 1 is a central vertical section showing a water closet bowl secured to a closet flange by a pair of anchoring devices;

FIGURE 2 is a side view of the bolt in a closet flange;

FIGURE 3 is a vertical section on line 33 of FIG- URE 2 showing a screw cast within the cap nut and screwed into lower tube section as seen from front of the closet.

FIGURE 4 is a fragmentary plan view on section 4-4 of FIGURE 1 showing the lower portion of the hold down device extending upward from a slotted closet or ring.

The anchoring device 1 passes freely through the usual standard holes in the flange 2 of the water closet bowl 3, having a head 4, a tubular portion 5 rising from a base 6 slidable in the slot of the brass flange 7. The two curved coaxial faces 8 provide a flat horizontal face or shoulder 9 rather snugly fitting flange 7 on the bottom surface It) of the latter.

A tapered screw 11 is embedded in the anchoring device head 4 so that its thread 12 cuts a groove 13 in the tubular portion 14 which originally has a smooth bore 15. The base of the lower piece 5-6 can pass readily through the large rectangular opening 18 and is then slid along the elongated arcuate slot 17 in flange 7 to the desired posh iiatented Apr. 27, 1965 tion where the head 4 with its permanently secured steel screw 11 may be turned as a nut, cutting a groove in and enlarging the diameter of the tubular portion, the recess 16 in the head providing ample vertical space to allow for any deviation in thickness of the vitreous flange of the bowl 3. While the lower enlarged portion or base 19 may be a surface of revolution, it is greatly preferred that it be shaped as shown in FIGURES 2 and 3, that is much wider parallel to the slot 17 as in FIGURE 2, and shorter where at right angles to the slot as in FIGURE 3. This configuration gives a more snug fit as the two faces 8 of the base are co-axial with the two inner margins of the slot 17.

What I claim is:

1. An anchoring member for securing a water closet bowl flange to a fixed ring below the bowl, said ring having two arcuate slots therein and said bowl flange being pierced by holes on opposite sides, comprising a two-piece bolt having an upper piece to engage the upper surface of the bowl flange and a lower piece adapted to project through and be held by one of said arcuate slots in the fixed ring and having an open end tubular portion extending vertically upward from the ring to extend loosely through one of the holes in the bowl flange and having initially a smooth cyclindrical inner wall, the upper piece including a tapered screw embedded in a hexagon head and adapted. to enter and cut a spiral groove in the smooth inner wall of the tubular portion of the lower piece as the head of said upper piece is turned, and upper piece having a central recess in its lower face to receive the top of the tubular portion of the lower piece whereby the anchoring member can be used with a series of different thicknesses of howl flanges with the head of the upper piece seated firmly on the top of the bowl flange and the top of the tubular portion of the lower piece within said central recess, the base portion of the lower piece being longer in the general direction of the arcuate slot than in a direction normal thereto.

2. The anchoring member of claim 1 in which the lower end of the lower piece is slotted on opposite sides by arcuate faces, said faces being co-axial with the sides of the arcuate slot in the ring.
